Brent Ozar and Thomas LaRock do a 3 part video series on the power of Policy-based Management (PBM). Interestingly SCOM comes up several times in the discussion.
They cover the basics of PBM and Thomas goes into more depth on how he’s using it in his environment. The series is about 35 minutes in total.
Regardless of your PBM experience level I highly recommend watching these videos.
